Description

Tangrid type package

The present invention relates to a package, and more particularly to a tan grid type package.

Various packaging containers have been developed in consideration of the properties of the goods. For example, when the product is a tobacco product such as a filter cigarette or cigarette, a tan grid type package is known as the packaging container.

Here, as one form of the tan grid type package, for example, a tan grid type package disclosed in Patent Document 1 has been proposed.

A conventionally known tan grid type package includes a box having an open end, a tan grid that opens and closes the open end of the box, and an item accommodated in the box. The item includes a bundle of a plurality of stick-shaped smoking articles. And a packaging material that wraps the bundle. In addition, this type of package is usually further encased by a transparent film, the film packaging having an opening tape.

JP-A-11-49134

By the way, it is preferable to omit the film packaging of the package in view of the recent demand for resource saving.

However, since film packaging is designed to maintain the hermeticity of the package so that atmospheric influences such as moisture and unpleasant odors in the environment do not reach the items in the package, If omitted, the quality of the items in the package may deteriorate.

The present invention has been made based on the above circumstances, and an object of the present invention is to provide a tan grid type package in which film packaging can be omitted.

In order to achieve the above object, the tan grid type package of the present invention has a rectangular parallelepiped shape, and is connected to a box body having an open end at the top and a rear edge of the open end via a lid hinge so as to be rotatable. A tongue that opens and closes the opening end, and a tongue connected to a tip of the lid via a tongue hinge, and when the lid is in a closed position, the tongue is a front wall of the box body A tan grid and a rectangular parallelepiped inner pack accommodated in the box body, wherein the inner pack is an article and an outer envelope for enclosing the article, and a wrapping material is wrapped around the article. The outer cover is formed by overlapping the outer peripheral edges of the packaging material, and has a seam line that forms the inside of the inner pack in a sealed space. That.

Since the inner pack described above wraps the product with the outer skin including the seam line that forms the inside in a sealed space by overlapping the outer peripheral edges of the packaging material, the sealing performance is improved.

Specifically, the seam line is formed by overlapping the edges of the packaging material and extends in the width direction on the front surface or the rear surface of the inner pack, and the same side of the packaging material. A pair of vertical seams formed by overlapping edges and extending along both side surfaces of the inner pack.

Preferably, the horizontal seam and the vertical seam have a fin seal shape. In this case, it is more preferable that the horizontal seam and the vertical seam are a horizontal seal and a vertical seal obtained by heat sealing.

According to this configuration, since the horizontal seal and the vertical seal are formed by heat sealing, the inner pack can be easily manufactured and the packaging efficiency of the product can be improved. And since the form of a fin seal is employ | adopted, the heat influence with respect to an internal item can be restrained low.

The tan grid type package of the present invention further includes an opening forming means for forming an access opening for exposing the product when the tan grid is first opened, the access opening being formed on the box body. The upper surface extends from the upper surface of the inner pack to the rear edge of the upper surface on the lid hinge side.

The above-mentioned opening forming means can easily form the access opening, so that the inner pack can be opened more easily.

According to the tan grid type package of the present invention, since the inner pack has high sealing performance, it is possible to suppress the deterioration of the quality of the goods accommodated therein. Therefore, the film packaging of the package can be omitted, which contributes to resource saving.

It is the perspective view which showed the tan grid type package which concerns on an Example in the state before opening. It is the perspective view shown in the state which opened the package of FIG. It is the perspective view seen from back lower side in the state which opened the package of FIG. It is the perspective view which showed the inner pack accommodated in the package of FIG. It is the figure which showed the packaging material of the inner pack of FIG. It is the figure which showed the main blank which forms the package of FIG.

FIG. 1 shows a package 2 of one embodiment.
This package 2 is a packaging container for storing tobacco products such as filter cigarettes and cigarettes, and has a rectangular parallelepiped shape as a whole.

The package 2 includes a box body 4 and a tan grid 6 connected to the box body 4, and the tan grid 6 has a lid 5 and a tongue 7.

As shown in FIG. 2, the box body 4 has a rectangular parallelepiped shape and includes an opening end 22 at the top, and the inside thereof has a size that can receive one inner pack 8. Specifically, the box body 4 includes a front wall 14, a rear wall 16, a pair of side walls 18 and a bottom wall 20.

As is clear from FIG. 2, the front wall 14 has a notch 24 at the upper center. This notch 24 forms part of the open end 22. The notch 24 has a substantially rectangular shape with its lower end edge bent into a flat V shape. Furthermore, the front wall 14 has a slit 26, which is positioned below the notch 24. The slit 26 extends along the lower end edge of the notch 24, has a flat V shape similar to the notch 24, and extends from one side edge of the front wall 14 to the other side edge. Here, the notch 24 is formed by separating the separation piece 28 having a shape corresponding to the notch 24 from the front wall 14, and the separation here is performed when the tan grid 6 is first opened. That is, immediately after the package 2 is manufactured, the scheduled separation region for forming the separation piece 28 is partitioned by the separation line in the upper center of the front wall 14. This separation line is formed from a perforated row, for example. The adjacent perforations in the perforation row may have a uniform length or have different lengths. The scheduled separation region can be easily separated from the front wall 14 along the separation line.

As is apparent from FIG. 3, the upper edge of the rear wall 16 is formed as a lid hinge 30. The tan grid 6 is rotatably connected to the rear wall 16 via the lid hinge 30. When the tongue grid 6 is rotated around the lid hinge 30, the lid 5 of the tongue grid 6 can open and close the opening end 22 of the box body 4, and when the opening end 22 is closed by the lid 5. The tongue 7 of the tan grid 6 is superimposed on the front wall 14.

More specifically, as is apparent from FIG. 2, the lid 5 has a rectangular shape having the same size as the opening end 22, and is provided with rectangular inner top flaps 32 on both sides of the back surface thereof. The inner top flap 32 is detachably connected to the upper end edge of the side wall 18 via a separation line, and immediately after manufacturing the package 2, the inner top flap 32 is overlapped on both sides of the upper surface of the inner pack 8. It is glued to. Therefore, when the tan grid 6 is first opened, the inner top flap 32 is separated from the corresponding side wall 18 along the separation line and is held on the back surface of the lid 5. Such an inner top flap 32 serves to reinforce the lid 5 and improve the formability of the box body 4.

Further, the lid 5 and the tongue 7 are connected to each other via a tongue hinge 34.
More specifically, the tongue 7 includes a tongue portion 36 and an insertion end 38, and the tongue portion 36 has a size covering the notch 24 and the scheduled separation region of the front wall 14. Specifically, the tongue portion 36 has a trapezoidal shape that is tapered toward the tip thereof, and the base end thereof is rotatably connected to the front end edge of the lid 5 via the tongue hinge 34. As is clear from FIG. 1, the tongue portion 36 has a semicircular recess 42 formed at the center in the width direction and in the vicinity of the tongue hinge 34. A portion corresponding to the recess 42 protrudes from the rear surface of the tongue portion 36.

As shown in FIG. 1, the insertion end 38 and the tongue portion 36 are partitioned via a hinge 44, and the insertion end 38 is rotatable around the hinge 44. The insertion end 38 has a base extending from the tip of the tongue 36 and a triangular tip extending from the base. That is, the side edge of the base portion at the insertion end 38 is positioned on the extension line of the corresponding side edge of the distal end portion of the tongue portion 36. For this reason, the tongue 7 has a shape that becomes thinner as it goes to the tip as a whole, and the insertion end 38 is easily inserted into the slit 26 of the box body 4 described above.

When the package 2 is manufactured, the reinforcing member 40 is connected to the base portion of the tongue portion 36 on both side edges thereof via separation lines. These reinforcing members 40 are in the shape of a right triangle with the tops cut off. Immediately after the manufacture of the package 2, the reinforcing member 40 is overlaid on and bonded to the side wall 18 on the corresponding side of the box body 4. That is, when the tongue grid 6 is opened for the first time, the reinforcing member 40 is separated from the tongue portion 36 along the separation line and remains on the side wall 18 to reinforce the opening end 22 and from the manufacture of the package to the tongue. Until the grid 6 is opened for the first time, the tongue 7 is held in close contact with the front wall 14 of the box body 4 to improve the sealing performance of the package.

Next, the inner pack 8 accommodated in the box body 4 has a rectangular parallelepiped shape as shown in FIG. The inner pack 8 includes a bundle of rod-shaped tobacco products 10 and a packaging material 12 that wraps the bundle. The tobacco product 10 is, for example, a filter cigarette having a length of 85 mm, and the number thereof is 20.

The packaging material 12 of the inner pack 8 has a rectangular shape and is folded around a bundle of tobacco products 10 to form an outer cover 13 that seals the bundle. More specifically, first, the packaging material 12 is wound around the outer periphery including the longitudinal direction of the bundle of tobacco products 10. Both ends of the wrapping material 12 are overlapped and bonded to each other at the upper part of the front surface of the bundle to form a so-called lateral seal 54 in the form of a fin seal. Such a lateral seal 54 extends over the entire width direction of the packaging material 12, and then, as is apparent from FIG. 4, the lateral seal 54 is folded toward the lower portion of the bundle and overlapped with the front surface 52 of the outer cover 13. Is done.

When the above-described lateral seal 54 is formed, the packaging material 12 forms rectangular portions that protrude from both sides of the bundle. These rectangular portions are subjected to gusset folding at the upper and lower sides thereof, and then folded to cover the side surfaces of the corresponding bundles to form the side surfaces of the jacket 13. The folding here forms a vertical seal 50 in the form of a fin seal at the center of the side surface of the outer cover 13, and the vertical seal 50 extends in the longitudinal direction of the bundle over the entire side surface of the outer cover 13. . Thereafter, the vertical seal 50 is folded, for example, toward the front surface 52 of the outer cover 13 as indicated by arrows A and B in FIG. 4 so as to be overlapped with the side surface of the outer cover 13. Is completed.

More specifically, the lateral seal 54 described above should be positioned above the lower end of the notch 24 of the box body 4 and below the opening end 22 when the inner pack 8 is accommodated in the box body 4. It is arranged, traverses across the entire width direction of the inner pack 8 from one vertical seal 50, and extends to the other vertical seal 50. Note that both end portions of the horizontal seal 54 are overlapped with the vertical seal 50.

Further, a flat, substantially M-shaped notch is formed at the center of the front edge of the horizontal seal 54, and this notch provides a V-shaped flap 56 to the horizontal seal 54. The contour of the V-shaped flap 56 matches the contour of the lower end portion of the notch 24 described above, that is, the contour of the lower end portion of the region to be separated.

Furthermore, the outer jacket 13 includes a scheduled separation region 60 that continues to the V-shaped flap 56. The planned separation region 60 has a belt shape, extends from the rear edge 58a of the upper surface 58 of the outer cover 13 to the front surface 52, and is partitioned by a pair of vertical separation lines 62 and horizontal separation lines. More specifically, the pair of vertical separation lines 62 extends upward from the corresponding end of the V-shaped flap 56 and further crosses the upper surface 58 to the rear edge 58a. Although the horizontal separation line is not shown in FIG. 4, it is formed along the proximal end of the portion of the horizontal seal 54 corresponding to the V-shaped flap 56 and extends between the pair of vertical separation lines 62. Here, the width dimension of the planned separation region 60, that is, the distance between the pair of vertical separation lines 62 is substantially the same as the width of the notch 24 described above.

Here, the pair of vertical separation lines 62 and horizontal separation lines are provided by weak lines provided in the packaging material 12. That is, if the vertical separation line 62 and the horizontal separation line are formed in a perforated row, the sealing performance of the inner pack 8 may be impaired. Therefore, the vertical separation line 62 and the horizontal separation line of the inner pack 8 are perforated. The column is not preferred.

FIG. 5 is a development view showing the inner surface side of the packaging material 12. A one-dot chain line in FIG. 5 indicates a fold line formed on the packaging material 12 when the bundle of tobacco products 10 is wrapped by the packaging material 12. As is clear from this development view, each region of the packaging material 12 defined by the folding line forms each part of the jacket 13 described above. Furthermore, the packaging material 12 has a heat seal layer of a heat-weldable film over the entire inner surface, and this heat seal layer enables the formation of the horizontal seal 54 and the vertical seal 50 described above.

More specifically, each region of the packaging material 12 includes a lower front region 64 that is a part of the front surface 52 of the outer cover 13, a bottom surface region 80 that is sequentially positioned above the lower front region 64 as viewed in FIG. It includes a region 86, a top surface region 92 and a top front region 98. The bottom surface region 80 forms the bottom surface of the jacket 13, and the rear surface region 86 forms the rear surface of the jacket 13. The upper surface region 92 forms the upper surface 58 of the outer cover 13, and the upper front surface region 98 forms the remainder of the front surface 52 of the outer cover 13. Further,

66, 82, 88, 94, 100 that form the side surface 48 of the jacket 13 are positioned on the left and right sides of the

regions

64, 80, 86, 92, 98, respectively.

As is clear from the above description, the lower end portion 54a of the lower front region 64 and the side region 66 and the upper end portion 54b of the upper front region 98 and the side region 100 are overlapped with each other and bonded to each other by heat sealing. A seal 54 is formed. In the left and right side regions, the outer edge portions 50a of the

side regions

66, 82, 88, 94, 100 on the same side are overlapped with each other and bonded to each other by heat sealing to form the vertical seals 50, respectively. The vertical seal 50 includes the end of the horizontal seal 54.

Further, as is apparent from FIG. 5,

notches

74 and 102 for the V-shaped flap 56 described above are formed at the lower end of the lower front region 64 and the upper end of the upper front region 98, while the lower portion In the front region 64, the upper front region 98, and the upper surface region 92, a vertical separation line 62 and a horizontal separation line, that is,

fragile lines

76 and 106 that define the above-described separation region 60 are formed.

Furthermore, the alternate long and short dash lines in the

side regions

82 and 94 indicate that the gusset folds are performed in the

side regions

82 and 94.

Next, FIG. 6 shows a main blank 108 for forming the box body 4 and the tan grid 6.

The main blank 108 has a front panel 110 that becomes the front wall 14 of the box body 4. The front panel 110 includes a scheduled separation region 112 of the box body 4 at a lower portion thereof. The scheduled separation region 112 is partitioned by a separation line 114 indicated by a broken line in FIG. In addition, a cut 116 serving as the slit 26 is formed in the upper part of the planned separation region 112.

In addition, an outer side flap 118 that is a part of the side wall 18 of the box body 4 is connected to both sides of the front panel 110, and a bottom panel that becomes the bottom wall 20 of the box body 4 is connected to the upper end of the front panel 110. 120 are connected.

The bottom panel 120 is connected to a rear panel 122 that is located on the opposite side of the front panel 110 and serves as the rear wall 16 of the box body 4.

The rear panel 122 is connected to a lid panel 124 that is located on the opposite side of the bottom panel 120 and serves as the lid 5. Further, inner side flaps 126, 126 which are the remaining portions of the side wall 18 of the box body 4 are connected to both sides of the rear panel 122. Inner bottom flaps 128 located on both sides of the bottom panel 120 are connected to the lower ends of the inner side flaps 126. The inner bottom flaps 128 are overlapped with the bottom panel 120 to reinforce the bottom wall 20. . Further, inner top flaps 32 located on both sides of the lid panel 124 are connected to the upper end of the inner side flap 126 via a separation line 130 indicated by a broken line in FIG.

A tongue panel 132 to be a tongue 7 is connected to the upper end of the lid panel 124. Reinforcing

member panels

134 and 134, which are the reinforcing members 40, are connected to both side edges of the tongue panel 132 via a separating line 136 indicated by a broken line in FIG.

On the other hand, in the case of the present embodiment, the main blank 108 is made of a paper material, and the weight thereof is 180 to 270 g / m ² and the thickness thereof is 0.2 to 0.5 mm. Specifically, the main blank 108 may be card paper, Manila cardboard, or the like.

The main blank 108 described above is folded from the folding line indicated by the alternate long and short dash line in FIG. 6 to form the box body 4 and the dangrid 6. By this folding, the tan grid 6 as shown in FIG. 1 is formed. The package 2 in a closed state is obtained.

More specifically, the inner pack 8 is placed on the rear panel 122. In this state, the inner side flap 126, the inner bottom flap 128, the inner top flap 32, and the bottom panel 120 are folded into the inner pack 8, respectively. The inner bottom flap 128 and the bottom panel 120 are bonded together. Further, after the front panel 110 is folded so as to cover the inner pack 8, the outer side flaps 118 are respectively folded, overlapped with the corresponding inner side flaps 126, and bonded to the inner side flaps 126.

Here, the V-shaped flap 56 of the inner pack 8 is bonded to the inner surface of the scheduled separation region 112. The inner pack 8 is bonded to the front panel 110, the rear panel 122, the bottom panel 120, the inner side flap 126, and the like as necessary. Next, the lid panel 124, the tongue panel 132, and the reinforcing member panel 134 are folded, and the lid panel 124 is bonded to the inner top flap 32. Further, the inner surface of the tongue panel 132 and the outer surface of the scheduled separation region 112 are bonded, and the reinforcing member panel 134 is bonded to the outer side flap 118. In this way, the package 2 containing the inner pack 8 shown in FIG. 1 is formed.

The consumer who has purchased this package 2 first picks up the tip of the tongue 7 and peels the tongue 7 off the front surface of the box body 4. Thus, the planned separation region 112 is separated from the box body 4 to form the cutout 24, and the planned separation region 60 of the inner pack 8 is separated. At the same time, the reinforcing member 40 and the inner top flap 32 on the side of the tongue 7 are also cut off at the same time. In this way, as shown in FIG. 2, when the tongue grid 6 is opened, the tobacco product 10 can be exposed through the access opening 63 formed by the separation of the scheduled separation area 60, and the consumer can access the access opening 63. The tobacco product 10 is taken out from 63. The separation piece 28 and the separation flap 60a formed by the separation of the separation planned region 112 and the separation planned region 60 are held on the inner surface of the tan grid 6 together with the V-shaped flap 56 (see FIG. 2).

Next, when closing the tongue grid 6, the lid 5 is put on the opening end 22, and the insertion end 38 at the tip of the tongue 7 is inserted into the slit 26. Thereby, the lid 5 is held in the closed position. At this time, the distal end of the insertion end 38 is narrowed, and the distal end of the insertion end 38 is directed toward the box body 4 by the action of the hinge 44, so that the insertion end 38 can be easily inserted into the slit 26.

When the tobacco product is taken out again, the consumer may hang a finger on the recess 42 provided on the surface of the tongue 7, pull out the insertion end 38 at the tip of the tongue 7 from the slit 26, and open the lid 5.
